By a News Reporter-Staff News Editor at Science Letter -- Current study results on Semiconductor Nanocrystals have been published. According to news originating from Changchun, People's Republic of China, by NewsRx correspondents, research stated, "This work reports the study of optimization of the reaction parameters on the synthesis of high quality CuInS2 and AgInS2 nanocrystals for bioimaging applications. The concentration of reaction precursors (e.g."
Our news journalists obtained a quote from the research from the Changchun University of Science and Technology, "Ag, Cu, In and S) plays a key role in determining the emission profile of these ternary quantum dots (QDs). By carefully varying the precursor compositions, the emission of QD can be tuned from red to near infrared (NIR) region. Taking the advantages of NIR emission, which possesses minimal absorption in biological tissues, we have also prepared water-dispersible CuInS2/ZnS and AgInS2/ZnS nanocrystals and demonstrated the high biocompatibility for both deep tissue penetration and tumor targeting. The QDs were stabilized in Pluronic F127 block copolymer micelles, offering us optically and colloidally stable contrast agents for in vitro and in vivo imaging. Two-photon excitation of QD has also been demonstrated, accomplishing a NIR-to-NIR transaction."
According to the news editors, the research concluded: "This study devotes the key steps in promoting the use of ternary QDs as low-toxic, photostable, and cadmium-free semiconductor nanocrystal formulation for multiple imaging applications."
